For each situation state which of the five quantities v0, vf, `ds, `dt and a are given, and give the value of each.
A ball accelerates uniformly from 10 cm/s to 20 cm/s while traveling 45 cm.
answer/question/discussion: ->->->->->->->->->->->-> :
v0=10
vf=20
'ds = 45
10 cm/2, 20 cm/s and 45 cm. The quantity is not complete without units.

A ball accelerates uniformly at 10 cm/s^2 for 3 seconds, and at the end of this interval is moving at 50 cm/s.
answer/question/discussion: ->->->->->->->->->->->-> :
a= 10cm/s^2
'dt= 3
vf=50

A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
answer/question/discussion: ->->->->->->->->->->->-> :
'ds=30
v0= 0
a= 20cm/s^2

Then for each situation answer the following:
Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> :
yes for the first one because you have vf and v0
and no for the next 2 because you do not have enough info.
#$&*
Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> :
yes for the first one because you have both the v0 and vf
and no for the next 2

Not bad, but check the discussion at the link related to what can be directly determined. Be sure to include units with quantities that have units. No revision is necessary unless you have questions.
